Kadın ilk çağlardan itibaren her alanda varlık savaşı vermiştir. Genel olarak varoluşlarından içgüdüsel bir şekilde şeyi paylaşan kadın ve erkeğin arasında, medeniyetlerin gelişimiyle, özellikle yönetim alanında büyük uçurum oluşmuştur. Zamanla erkek egemen toplumlar meydana çıkmış kadınlar yönetimde arka planda kalmışlar, çoğu zaman egemenliği üzerinde genel tahakküm kurmuştur. Fakat mücadeles...

This paper describes a two-pass implementation of a physics-based global lighting model. This latter uses a physics-based reflection model, spectral distribution of light powers, and does not make any assumption on the specular behavior of materials. The scenes are discretized into points instead of patches . Hence, any kind of surface can be used without having to break down it into small plan...

An expression for the kth power of an n×n determinant in n2 indeterminates (zij) is given as a sum of monomials. Two applications of this expression are given: the first is the Regge generating function for the Clebsch-Gordan coefficients of the unitary group SU (2), noting also the relation to the 3F2 hypergeometric series; the second is to the even powers of the Vandermonde determinant, or, e...

In this paper, we propose a generic hybrid oriented-transform and wavelet-based image representation for intra-band image coding. We instantiate for three popular directional transforms having similar powers of approximation but different redundancy factors. For each transform type, we design a compression scheme wherein we exploit intra-band coefficient dependencies. We show that our schemes o...

Abstract This paper proposes a voltage and frequency controller for a wind turbine-driven independent asynchronous generator. The proposed controller consists of IGBT (Insulated Gate Bipolar Transistor) based three phase voltage source converter along with battery energy storage system at its DC bus and it inherently adapts to the changes in the rotor speed while maintaining a near constant vol...

This paper offers an algorithmic solution to the problem of obtaining “economical” formulae for some maps in Simplicial Topology, having, in principle, a high computational cost in their evaluation. In particular, maps of this kind are used for defining cohomology operations at the cochain level. As an example, we obtain an explicit combinatorial description of all Steenrod kth powers exclusive...

Let Q(k, l) be a poset whose Hasse diagram is a regular spider with k+1 legs having the same length l (cf. Fig. 1). We show that for any n ≥ 1 the nth cartesian power of the spider poset Q(k, l) is a Macaulay poset for any k ≥ 0 and l ≥ 1. In combination with our recent results [2] this provides a complete characterization of all Macaulay posets which are cartesian powers of upper semilattices,...

We investigate the Waring-Goldbach problem of representing a positive integer n as the sum of s kth powers of almost equal prime numbers. Define sk = 2k(k − 1) when k > 3, and put s2 = 6. In addition, put θ2 = 19 24 , θ3 = 4 5 and θk = 5 6 (k > 4). Suppose that n satisfies the necessary congruence conditions, and put X = (n/s). We show that whenever s > sk and ε > 0, and n is sufficiently large...

Broadcast domination was introduced by Erwin in 2002, and it is a variant of the standard dominating set problem, such that vertices can be assigned various domination powers. Broadcast domination assigns a power f(v) 0 to each vertex v of a given graph, such that every vertex of the graph is within distance f(v) from some vertex v having f(v) 1. The optimal broadcast domination problem seeks t...
